It is a common practice to measure an aero thirteen rods each way ; that 

 gives an excess of nine rods. At the South, it U common to measure scvcnly 

 yards each way for an acre, which is an excess of 540 yanls. In calculating 

 the number of plants per acre, set four feet ai)art— for instance, cabbag».«»— 

 it is common to Siiy ten thousand per acre. Tiiis allows nearly nine hundred 

 missing plants. In garden work lliese rules will always l>e useful.
